The Effect of Electrical Anisotropy and Acoustic Inhomogeneity in Magnetoacoustic Tomography with Magnetic Induction

Magnetoacoustic tomography with magnetic induction(MAT-MI) is a noninvasive technology for imaging the distribution of electrical impedance in biological tissue. In the sameple, a time-varying magnetic field induces currents. A static magnetic field interact with the currents to produce a Lorentz force. Consequently, the sample will emit ultrasonic waves by the Lorentz force. The objective of t...

Electric Impedance

Electrical impedance tomogram of the mammary gland (EIM). Seven planes of scanning. In the sixth and the seventh scans, a retromammary tissue is visualized. It can be used to distinguish tissues and identify pathologies. Lorentz force electrical impedance tomography is an ultrasoundbased medical imaging technique. In this study, a new platform based on electric cell-substrate impedance sensing ...

Magnetoacoustic tomography with magnetic induction (MAT-MI) for imaging electrical conductivity of biological tissue: a tutorial review.

Magnetoacoustic tomography with magnetic induction (MAT-MI) is a noninvasive imaging method developed to map electrical conductivity of biological tissue with millimeter level spatial resolution. In MAT-MI, a time-varying magnetic stimulation is applied to induce eddy current inside the conductive tissue sample. In the presence of a static magnetic field, the Lorentz force acting on the induced...

The Application of Multi-Layer Artificial Neural Networks in Speckle Reduction (Methodology)

Optical Coherence Tomography (OCT) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. An inherent characteristic of coherent imaging is the presence of speckle noise. In this study we use a new ensemble framework which is a combination of several Multi-Layer Perceptron (MLP) neural networks to denoise OCT images. The noise is...
